GPUtest- FurMark
This is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that's why FurMark is also a perfect stability and stress test tool for the graphics card. We ran the test at 2560x1440 Windowed with anti-aliasing disabled. (HIGHER number means FASTEST in Frames Per Second.)

GPUtest- TessMarkTessellation is the ability of the GPU to divide a polygon into smaller ones (according to the tessellation level factor) in order to increase polygons density: the higher the tessellation level, the higher the polygon density. A high tessellation level requires much GPU processing power. We chose 16 levels (usually the max that games use) at 2560x1440 Windowed with anti-aliasing disabled. (HIGHER number means FASTEST in Frames Per Second.)
